# Fisher's Iris Data Base of 1936

(Redirected from iris dataset)

Fisher's Iris Data Base of 1936 is a small low-dimensional i.i.d. data base that represents Iris presented in (Anderson, 1935) and made famous by (Fisher, 1936).

**Context:**- It can be used in a Iris Dataset-based Classification Task, Iris Dataset-based Clustering Task, ...
- It can be attributed to (Anderson, 1935).

**Example(s):****Counter-Example(s):****See:**UCI Dataset, Benchmark Data, Fisher's Discriminant Analysis, Iris (Plant).

*Iris*(*Iris setosa*,*Iris virginica*and*Iris versicolor*). Four features were measured from each sample: the length and the width of the sepals and petals, in centimeters. Based on the combination of these four features, Fisher developed a linear discriminant model to distinguish the species from each other.

- This is perhaps the best known database to be found in the pattern recognition literature. Fisher's paper is a classic in the field and is referenced frequently to this day. (See Duda & Hart, for example.) The data set contains 3 classes of 50 instances each, where each class refers to a type of iris plant. One class is linearly separable from the other 2; the latter are NOT linearly separable from each other. …
